System stability issues since installing a 5900x

Ryzen 9 5900x problems

hey there, noob questions incoming, would love to get some help.

Bought the 5900x yesterday to replace my 3700x. Motherboard is a Gigabyte B450M DS3H. Immediately started having problems once swapping the two. Successfully flashed the BIOS, then got it to post. After testing Modern Warfare 2 I blue screened and couldn’t get it to post at all, just a black screen, no BIOS. After an hour or so of trying we pulled ram from 1 and 3 and it posted. Wasn’t aware that 2 of my ram sticks didn’t match the other. 2 Corsair vengeance DDR4 3600MHz and 2 Corsair vengeance DDR4 3200MHz. So would that be a memory leak? I have the two 3600 ones in right now in slots 2 and 4. Temps are in the high 70’s mid 80’s most of the time gaming or downloading. I know it runs hot but I’m not sure if that’s bad for it? Using a thermal-take water 3.0 120mm for the CPU as well. Idle temps were like 50 and up. I saw on another forum the VRM on this B450M might not be ideal with the 5900x? Lol I have no idea what I’m doing any help would be rad. Not sure if I should just return it and wait until I can get a new motherboard? Or if it might be a psu issue? Thanks in advance!

Smelliot, different memory is definitely a bad idea.Memory leak???, no. Temperatures  of 70s and 80s are ok,but be sure your cooler is tight and all fans are running. If the VRM were a problem you would be crashing. Please post screenshots of Ryzen Master both Basic and Advanced views, images of RM only. Thanks, John.
